Ok, I am a novice with regard to bike components. I purchased a used 2007 Trek 7.6 FX for $400. The bike is in like new condition. I had a tune-up at the LBS and the tech said that the bike is in mint condition.
My question is about the crankset. My 2007 Trek 7.6 FX has a Bontrager Select 36/50 teeth crankset with 9-speed rear cogs, 11-26 teeth. I have noticed that the 2008 Trek 7.6 FX has a Shimano FC-M443 26/36/48 teeth with 9-speed rear cogs, 11-26 teeth. Why would my 2007 Trek FX have a 36/50 crankset instead of a 26/36/48 crankset? Is having only 18 speeds a significant disadvantage compared to having 27 speeds?
Just wondering if I bought into a bad year.
